Resistors

KEVLIN - 5089-P - Current Sensor Resistor. 0.01-Ohm.

Current sense resistors are often referred to as 'shunt' resistors. Shunt resistors are used to monitor the amount of current that is flowing through a circuit. Such resistors have very low resistance values, typically less than 50 milli-ohms (0.050 ohms) and often lower.

A 'Kelvin' configuration resistor features four leads or terminations. These four terminal resistors enable current to be applied through two opposite leads and a sensing voltage to be measured across the other two leads. The Kelvin configuration effectively eliminates the resistance and temperature coefficient of the leads. The Kelvin connection can also simplify board design by incorporating all terminals for the sensing circuit into one part. A Kelvin connection is essential for accurate current sensing and simplified board design.

Tolerance: 1%.
